standards. The fireplace must always be installed in compliance with
naonal laws and regulaons. Always contact your local fire safety
office about current regulaons before installing your fireplace.
Read the Installaon instrucons with technical data and the
General informaon and maintenance manual carefully before
starng assembly/installaon.
A rang plate made of a heat-resistant material comes with

Operaon Intermient*
*Intermient operaon means normal use of a fireplace, i.e. add
more fuel as soon as the fire has burned down to embers.
Performance declaraon and declaraon
of conformity can be found on Jøtul’s
website.
Register your fireplace at www.jotul.com
to get a 25-year guarantee.
The serial number and year are
marked on a label on all our
products. Write this number in the
place indicated in the Installaon
instrucons.
This serial number must always be
quoted when contacng your dealer
or Jøtul.

SAFETY
NB: To guarantee opmal performance and safety, Jøtul
recommends that its stoves are fied by a qualified installer (see
www.jotul.com for a complete list of dealers).
Any modificaons to the product by the distributor, installer
or consumer may result in the product and safety features not
funconing as intended. The same applies to the installaon of
accessories or oponal extras not supplied by Jøtul. This may also
be the case if parts that are essenal to the funconing and safety
of the fireplace have been disassembled or removed.
In all these cases, the manufacturer is not responsible or liable for
the product and the right to make a complaint becomes null and
void.
FIRE PREVENTION MEASURES
There is a certain element of danger every me you use your
fireplace. The following instrucons must therefore be followed:
The minimum safety distances when installing and using the
fireplaces are given in the figures on the following pages.
• Ensure that furniture and other combusble materials are not
too close to the fireplace. Combusble materials must not be
placed within 1,000 mm of the fireplace opening.
• Allow the fire to burn out. Never exnguish the flames with
water.
• The fireplace becomes hot when lit and may cause burns if
touched.
• Only remove ash when the fireplace is cold. Ash can contain
hot embers and should therefore be placed in a non-flammable
container.
• Ash should be placed outdoors or be emped in a place where
it will not pose a potenal fire hazard.
In case of a fire in the chimney:
• Close all openings and valves.
• Keep the door to the firebox closed.
• Call the fire department.
• Ensure that the fireplace and the chimney are inspected and
given a green light by a professional before you start to use the
fireplace again aer an outbreak of fire.
FLOOR
Foundaons
You must make sure that the foundaon is suitable for the fireplace.
See “Technical Data” for specified weight.
We recommend the removal of any flooring that is not aached to
the foundaon (“floang floors”) beneath the installaon.
Requirements for protecon of combusble
floors under the fireplace
The product can be installed directly on a combusble floor that
is covered by a sheet of metal or other non-flammable material.
Recommended thickness is a minimum of 0.9 mm).
The funcon of a floor plate is to protect the floor and flammable
materials against embers. Jøtul recommends that floor covering
made of flammable material, such as linoleum, carpets, etc., be
removed from under the floor plate.
The floor plate must comply with naonal laws and regulaons.
Contact your local building authories regarding restricons and
installaon requirements.
For Norway: Minimum 300 mm in front of the door and width at
least the same as the door.
WALLS
• Place the product in such a way that it is possible to clean the
stove, the flue pipe and the chimney passage.
• Ensure that furniture and other combusble materials are not
too close to the fireplace.
• Make sure that furniture and other household items are not so
close as to get dried up by the stove.
Distance to walls made of combusble material – see the figures on the
following pages.
The distances relate to a shielded flue pipe/semi-insulated pipe.
The fireplace can be installed with an uninsulated flue pipe. In this case,
the flue pipe must be CE marked and the pipe’s declared distance to
flammable materials must be taken into consideraon.
Combusble wall protected by firewall
Distance to combusble wall protected by firewall – see the figures
on the following pages.
Requirements for firewall
The firewall must be at least 110 mm thick and made of brick,
concrete or lightweight concrete. Other materials and structures
with sasfactory documentaon may also be used, e.g. 50 mm Jøtul
Firewall.
Non-flammable materials refer to materials that cannot burn, e.g.
bricks, les, concrete, mineral wool, various silicate plates, etc. Bear
in mind that a short distance to non-flammable walls can result in
the drying out and discolouraon of paintwork, as well as lead to
the formaon of cracks.
CEILING
There must be a minimum distance of 750 mm between the
fireplace and a ceiling made of a combusble material above the
fireplace.

INSTALLATION
CHIMNEY AND FLUE PIPE
• The fireplace can be connected to a chimney and flue pipe approved for solid fuel fireplaces with flue gas temperatures as specified in “Technical
Data”. If a steel chimney is used, this must be marked with T 400 and G for soot fire tesng.
• The cross-secon of the chimney must be at least as large as that of the flue pipe: Ø150 mm flue pipe- 177 cm2.
• Several solid fuel stoves can be connected to the same chimney system if the chimney cross secon is adequate.
• The specified distance to combusble materials applies to this stove.
• Use a CE approved flue pipe and/or steel chimney.
• Take into account the distance from the flue pipe to combusble materials.
• The chimney must be connected in accordance with the installaon instrucons of the chimney supplier.
• Before a hole is made in the chimney, the fireplace should be test-mounted in order to correctly mark the posion of the fireplace and the hole
in the chimney. See “Dimensional diagram and assembly distances” for your stove for minimum dimensions.
• Use a flue pipe bend with a sweep hatch to allow sweeping.
• Numerous flue bends (and flue bends of many degrees) can affect the draught in the chimney. The same can occur in the case of long horizontal
lengths. Please note that it is extremely important for connecons to have a degree of flexibility. This is to prevent any movement in the
installaon leading to the formaon of cracks.
• For recommended chimney draught, see “Technical Data”. For flue pipe dimensions, see “Technical Data”.
NB: The minimum recommended chimney length is 3.5 m. If the draught is too strong, a flue pipe damper can be installed and used to reduce the
draught.
When installing a flue pipe damper, this must be of the type that does not close the flue pipe fully. The damper must be easy to operate, and must
have a free opening of at least 20 cm2, or 3% of the flue pipe’s cross-secon if this is larger. The posion of the damper must be visible when
operang the stove. If a draught regulator is installed, the requirement regarding the free cross-secon does not apply, although the unit must be
easily accessible for cleaning.

12
PRIOR TO INSTALLATION
• Before installing the fireplace, check it carefully for any signs of damage
• The product is heavy! Ask someone to help you when posioning and installing it. We recommend using a liing device.
• Make sure that furniture and other household items are not so close as to get dried up by the stove.
Remove the transport brackets
• The standard product comes in two packages. One contains the fireplace itself, the other contains the base or pedestal in cast iron.
• Remove screws from the brackets to release the burn chamber from the pallet.
• The burn chamber must be laid on its back to secure the base. Before doing this, loose parts should be dismantled. Dismantling is presented
on page 34.
• Exercise cauon when dismantling the parts.
